The hazmat suit is a thick rubber suit which fully encases the body (consuming the use of the body slot and preventing the user from wearing armor). It has a plastic visor to let the user see through, and thick rubber gloves. The hazmat suit is not considered armor and provides no armor bonus, but does provide a +5 circumstance bonus on Fortitude saves vs poison and disease. The bonus only applies if you are struck with the poison or disease while you are wearing the suit, you gain no benefit putting the suit on after you are already poisoned or diseased.

Due to it's bulk, you take a -1 armor check penalty, and donning and removing the suit takes as much time as donning or removing breastplate.
